Procedure
1. Choose Device Tools → Configuration → Process Measurement → Concentration Measurement.
The Concentration Measurement window is displayed. It is organized into steps that allow you to
perform several different setup and configuration tasks. For this task, you will not use all the steps.
2. Scroll to Step 4.
3. Choose the method to be used to supply temperature data, and perform the required setup.
Option Description Setup
Internal
temperature
Temperature data from
the on-board temperature
sensor (RTD) will be used
for all measurements and
calculations. No external
temperature data will be
available.
a. Set Line Temperature Source to Internal.
b. Click Apply.
Polling The meter polls an external
device for temperature data.
This data will be available in
addition to the internal RTD
temperature data.
a. Set Line Temperature Source to Poll for External Value.
b. Set Polling Slot to an available slot.
c. Set Polling Control to Poll as Primary or Poll as Secondary.
Option Description
Poll as Primary No other HART masters will be on the
network. A field communicator is not
a HART master.
Poll as Secondary Other HART masters will be on the
network. A field communicator is not
a HART master.
d. Set External Device Tag to the HART tag of the temperature
device.
e. Click Apply.
Digital
communications
A host writes temperature data
to the meter at appropriate
intervals. This data will be
available in addition to the
internal RTD temperature data.
a. Set Line Temperature Source to Fixed Value or Digital
Communications.
b. Click Apply.
c. Perform the necessary host programming and
communications setup to write temperature data to the
meter at appropriate intervals.
Postrequisites
If you are using external temperature data, verify the external temperature value displayed in the Inputs
group on the ProLink III main window.
Need help?
If the value is not correct:
• Ensure that the external device and the meter are using the same measurement unit.
• For polling:
— Verify the wiring between the meter and the external device.
— Verify the HART
®
tag of the external device.
